Greenhouse Cooling System
The negative pressure fan / forced air exhaust fan uses the cooling principle of air convection and negative pressure ventilation. It is a kind of natural inhalation of fresh air from the opposite side of the installation site — the door or window, and the indoor sultry gas is quickly forced out of the room. Any poor ventilation problems will be eliminated. The machine can be improved, and the cooling and ventilation effect can reach 90%-97%.
The whole fan adopts CAD/CAM design, which has the characteristics of low investment cost, large air volume, low noise, low energy consumption, stable operation, long life and high efficiency. It can also be ventilated, which is the best choice for cooling and ventilation of modern greenhouses. Environmentally friendly and energy-saving negative pressure fans will become the mainstream of the ventilation and cooling equipment market.
Use with wet curtains / evaporative cooling pad : Used for workshop cooling in hot summer, no matter how hot your workshop is, the wet curtain-exhaust fan system can reduce the temperature of your modern greenhouses to about 30C, and there is a certain humidity.
The motor of the medication blower adopts the IP54 and F-class insulation fan special-purpose aluminum shell motor produced by advanced technology. It has the function of under-phase overload protection, long service life, stable operation and low noise.
The cooling principle of the exhaust fans :
The negative pressure fan uses the cooling principle of air convection and negative pressure ventilation. The opposite direction of the installation site—the door or window naturally inhales fresh air, and quickly forces the indoor stuffy air out of the room. Any poor ventilation problems can be improved, and the cooling and ventilation effect can reach 90%-97%.
The powerful advantages of exhaust fans:
1. Less investment and low energy consumption. The same cooling rate, the one-time investment is about one-sixth of the air conditioner, and the operating cost is about one-tenth of the air conditioner;
2. The cooling effect is remarkable, and the temperature can be reduced to about 28 degrees, which is consistent with the temperature of the human body. If the water in the well is used as the source of the water tank, the effect is better, and the effect can be compared to that of an air conditioner;
3. The air is fresh and humid, and the air cleanliness can reach 99%.
The negative pressure fan discharges air outwards to reduce the indoor air pressure, and the indoor air becomes thinner, forming a negative pressure area, and the air flows into the room due to the compensation of the air pressure difference.
In the actual application of the greenhouse, the negative pressure fan is installed on one side of the greenhouse, and the air inlet is on the other side of the factory building, and the air is blown by convection from the air inlet to the exhaust fan . During this process, the doors and windows near the negative pressure fan are kept closed, and the forced air flows into the greenhouse from the doors and windows on the side of the air inlet. The air flows into the greenhouse from the air inlet in an orderly manner, flows through the greenhouse, and is discharged from the greenhouse by the negative pressure fan.
The ventilation is thorough and efficient, and the ventilation rate can be as high as 99%. Through specific engineering design, design the ventilation speed and wind speed according to the needs, any high heat, harmful gas, dust and smoke can be quickly discharged from the workshop, and any problem of poor ventilation can be completely solved at one time. The ventilation effect can be achieved within a few seconds from turning on the fan.
Thus providing the freshest air needed for the healthy growth of various plants, vegetables, fruits, flowers, etc. grown in the greenhouse.
